3 Claims.

This invention relates to forming and treating filaments in so-called rock Wool manufacture.

This invention has utility especially in continuous' manufacture from fusing to threading and placing the product into merchantable shape,

' say as mineral wool. Y

Referring to the drawing Fig. 1 is a. section near the discharge portion of a/fusing chamber or cupola showing an embodiment of the invention from the fused flow to the,V

filament forming nozzle; y

Fig. 2 is a section on the line X-X, Fig. 1,

showing the relation of the iiow or spreader plate to the nozzles and adjustable mountings.

Raw material descends in cupola 3 having water .jacketed sides 4. This cupola 3 is carried on frame members 5 supported by corner columns 6.l Pressure blast 1 promotes combustion to fusing temperature in the cupola 3 to such extent that as the mass descends to re brick lined region 8, there may be a molten, fused, or liquid mass 9 to ilow over oor I0 having thickened out- Rising f1 om this iioor I0 is wall I2 having offset I3 from the forward or outward edges of the ledge II. 'This wall I2 provides bounds for port I4 iiush with the door III and with height above that of the molten mass 9 providing gas blow region I5 over ilow I6 of the molten siliceous mass. This floor, ledge,4 and Wall structure I0, II,I2may be desirably of therein for providing said pressure channel of steamas an effective carrier and lament proj ducer in ,blowing into oracross a descending melt CFI 2'1. There is formed, transversely of the stream, a filament mass 33. Supporting each steam pipe 28 is rod 34 having anchor 35 therewith, such rod having handle 36, and remote therefrom, stem ,portion 31 in an opening 38 of a strap 39 from the frame 5. Each rod 34, adjacent the handle, has

weight 4II- as a load against casual disturbance. One grasping the'handle and thrusting such toward the nozzle may thereby adjust the height of the nozzle as to the stream 21 asthe pipes 28 are slightly off horizontal. If there be occasion to adjust the nozzle more nicely into the stream laterally thereof, this iseiected by pushing or pulling on the handle 3i, in thereby thrusting the terminal 31 further into the opening 38 or withdrawing suchslightly. This means that as to each nozzle there is a nicety of accurate control by a single handle for. the multiple positions of the nozzle as to the descending melt.

The multiple blasts 33 are herein shown as upwardly directed.

metal, such as cast iron, .with sufficient body to thus permitted desired adjustment for locating portion 25 from the plate I9 as a stream divider directly below thestream I6, for dividing such molten iiow that approximately evenportions thereof may pass down the respective inclines to drop 21 therefrom. With the contour herein disclosed there is a maintenance factor for Acontinuity of operation and effective response in increasing flow-off of the melt from the cupola and effectively caring for such melt by pressure nozzle filament-forming action so effective transversely of such descending portions 21 as to completely and fully intercept the flow.

Herein steam lines 28 extend under the cupola and have offsets 29 'toward each other with threaded upwardly directed termini 30,-on which may be .located caps 3| each having V-nozzle 32 55 The-disclosure herein is one of manufacturing emciency of importance in the insulation eld and permits the economical production of a high grade product vwith efficiency in melting, in

gathering, and placing into merchantable 'or a product having superir attributes.

In the operations hereunder, the step of charging the cupola is such as to-maintain the-flow bed of say 1 inch depth for the stream Ii in ilow through a port I4, say 1 inch wide and 2% inches high, the blast thereover being such as not to carry impurities. This iiow stream of mass to be lshredded has such divided for eflicient shred or to said nozzle, and means for supporting the handle for movement in two directions at right angles to each other.

2. An attachment for a furnace comprising a' pipe, a-movable nomle connected to the pipe and positioned for directing a jet of gaseous iiuid on a stream of molten materials ilowing from the furnace for shredding the stream of molten materials into bers, an actuating member, means for supporting the actuating member, said actuating member being swingable and longitudinally slidablerelatively to the supporting means, and means for operatively connecting the actuating member with the nozzle for adjustably positioning the nozzle relatively to the stream of molten materials when the actuating member is swingably or slidably moved.
